This is what a successful relationship is, two paths of destiny forged by each individual person involved which traverse together, which enjoy a considerable amount of overlap, enough that they may respectively create their lives while empowered by a force that’s greater than they themselves could alone achieve.
That is exactly how all relationships should be; i.e. 50/50. Any couples holds 3 persons, each individual and both of them together. Hence each individual should continue to live their passions/interests individually but also have common passions/interests together.
